O-Rings FAQ Section
How do I choose the right O-Ring material for my application?
Selecting the appropriate O-Ring material depends on three key factors: the operating temperature range, chemical exposure, and pressure requirements. For petroleum-based fluids, Nitrile (NBR) is typically recommended. For high-temperature applications with aggressive chemicals, Viton® (FKM) offers superior performance. Always consider the compatibility charts and consult with our technical team for specific application requirements.
What causes O-Ring failure and how can I prevent it?
Common causes of O-Ring failure include improper sizing, chemical incompatibility, excessive temperature exposure, and incorrect installation. To prevent premature failure: ensure proper groove design, select material compatible with your operating environment, follow proper installation procedures, and consider environmental factors like UV exposure or ozone levels that might degrade the material over time.
